TRAILER MAINTENANCE Lug Nut Torque Requirements It is extremely important to apply and maintain proper wheel mounting torque on the trailer. Be sure to use only the fasteners matched to the cone angle of the wheel. Proper procedure for attachment of the wheels is as follows: Start all wheel lug nuts by hand.
TROUBLESHOOTING (GENERATOR) Practically all breakdowns can be prevented by proper handling and maintenance inspections, but in the event of a breakdown, use Table 19 shown below for diagnosis of the Generator. If the problem cannot be remedied, consult our company’s business offi ce or service plant. Table 17.
TROUBLESHOOTING (ENGINE CONTROLLER) Practically all breakdowns can be prevented by proper handling and maintenance inspections, but in the event of a breakdown, use Table 20 (Engine Controller Troubleshooting) as a basic guideline for troubleshooting the Microprocessor Engine Controller unit (MPEC). If the problem cannot be remedied, consult our company's business offi ce or service plant. Table 18.
TROUBLESHOOTING (DIAGNOSTIC LAMP) The engine controller of this generator diagnoses problems that arise from the engine control system and the engine itself. Press the diagnostic button (Figure 66) on the diagnostic panel to determine if an engine malfunction has occurred. Figure 66.
